@Orizielle Hi! Thank you so much for reading, and your wonderful comments! I'm sorry for not replying sooner, I'm not as active on this site as I used to be.
As for the answer to your question, for me personally, I wanted to deal with emotions and concepts in this book, rather than people and things. That's why I made everything so abstract and open to interpretation, never mentioning names or specifying locations, appearances or genders. That is also why I love it when readers come to me with their interpretations. I have never heard two interpretations that were the same, and it always fills me with wonder how there can be so many different metaphors for the same story in the minds of different people, yet each one being equally plausible.
Yours is definitely a great one, I love it!
